iPhone 5 low resolution and blur image in every lcd

Texte:

I have a customers iPhone 5 that dropped from his hand. When I received the phone I thought it was only the LCD that need replacement, I put other LCD but still the phone has low quality image, low resolution and blur image. I replace the LCD again but still the same, I test the LCDs in other iPhone 5 and working great. I checked the FPC connector and has no damage. Can you please help me, what do you think is the problem? Is there any damage IC? Any damage resistor? Where I suppose to look?
 
Please take a look at this photos

This missing part seems to be the Capacitor C440. Do you think this cause the problem? How can i fix this? Is it neccesary to find the same capacitor? Is this capacitor polarized or i can install it in any direction?
 
Thanks for your help!!!
